One night I was doing routine checks on my car when I noticed one of the high beams were out. Initially I didn't think anything of it considering I only glanced so naturally I thought I was seeing things. So after properly checking I noticed that there's a faint orange glow coming from the high beam when I turned it on. My cousin's first thought was that I needed to change the bulb but I was like "but if it needs to be changed it shouldn't get current should it!?". So the next day I did a complete checkup on my fuses. SRS was blown (fixed that....there's another one blown but I don't remember what it is but remember it's not urgent replacement stuff, I think it's the running light or something....). Anyway, so I got to the R H/L beam fuse and the top part got reading on the test light but the bottom part didn't. I then removed the fuse and saw the bottom part of it was broken inside; so I changed the fuse and would you believe it?, it blew AGAIN right before my ears (lol). So.....I changed that fuse, same thing, and did that two more times.....after that I decided to leave it alone seeing that fuses aren't that cheap here and I was getting nowhere. I disconnected my hood lights, fog lights, and some other lights I have on my wipers cause I thought there may have been a load but still the same problem. I'm pretty puzzled at this point because I also checked all the wiring (took me about 4 hrs) and everything seems A-OK in terms of the lights but maybe I'm missing something.

 

Unplug the bulb, pull the fuse and check resistance from the terminal for the "cold" end of the fuse (the one that goes to zero volts when it's blown, which leads to the bulb) to ground. Should be open circuit if that part of the wiring is stock. If shorted, find the short in the wiring. If it is open try a new bulb (seems unusual for a bulb to fail shorted, but anything's possible). Could also be an intermittent short up at the bulb socket that goes away when you move the plug.

 

This is almost certainly due to an electrical short on the circuit protected by the fuse that keeps blowing. Double check all wiring on the circuit as well as the connector(s) at each component. The short might be located by looking for damaged and burnt wires.

 

Thanks alot you guys, first chance I get I will look into it. Since I have halos, it will be a huge pain removing the bulb as I always have to unbolt the fenders then the headlights just to get to anything in it. First I will re-check the wiring like RonJ suggested. Hopefully I can avoid having to go to an auto electric shop.

 

If you don't find the electrical short in either the wires or the connectors, as I mentioned, then consider mk378's point that the short also could be occurring at the bulb socket.
